Find more reliable and universal way to get ASN and ASorg mappings
This ticket is intended to continue the discussion started at #19420 (moved) about GeoIP database reliability. To outline:
- We use only one source of ASN mappings (MaxMind's GeoIP)
- This source became unreliable recently (#19154 (moved), #19420 (moved))
- The data is maintained manualy and this process is pretty crafty. So it's good to move this process to vcs like Git.
